Ni iyihe nzitizi ya clamp kuri ultrasound flowmeter?

Ingorane zihari muri iki gihe za ultrasound flow meter ni uko ubushyuhe bw'umubiri upimwe bugengwa n'ubushyuhe bwa aluminium ikoreshwa mu gukwirakwiza ingufu za ultrasonic n'ibikoresho bihuza transducer n'umuyoboro, kandi amakuru y'umwimerere y'umuvuduko wo kohereza amajwi y'umubiri upimwe ku bushyuhe bwinshi ntabwo yuzuye. Kuri ubu, Ubushinwa bushobora gukoreshwa gusa mu gupima amazi ari munsi ya 200°C. Byongeye kandi, umurongo wo gupima wa ultrasound flow meter ugoye kurusha uw'umurongo rusange w'umuvuduko. Ibi biterwa nuko umuvuduko w'amazi mu gupima muri rusange mu nganda akenshi uba metero nke ku isegonda, kandi umuvuduko wo gukwirakwiza w'umuvuduko w'amajwi mu mazi ni hafi 1500m/s, kandi impinduka mu muvuduko w'amajwi uterwa n'impinduka mu muvuduko w'umubiri upimwe w'umuvuduko nazo ni 10-3 z'ubunini. Niba ukuri kw'igipimo cy'urujya n'uruza rw'amajwi ari 1%, ukuri kw'igipimo cy'umuvuduko w'amajwi bigomba kuba hagati ya 10-5 ~ 10-6, bityo hagomba kubaho umurongo utunganye wo gupima kugira ngo ugerweho, ari na wo mu gipimo cy'urujya n'uruza rw'amajwi gishobora gukoreshwa gusa mu iterambere ryihuse ry'ikoranabuhanga rya "integrated circuit".
(1) Ingano y'ubushyuhe bw'icyuma gipima ubushyuhe cya ultrasonic ntabwo iri hejuru, kandi muri rusange ishobora gupima gusa ibinyabutabire bifite ubushyuhe buri munsi ya 200 ° C.
(2) Ubushobozi buke bwo kurwanya ingaruka mbi. Biroroshye kubangamira urusaku rwa ultrasound ruvanze n'udupira, ingano, pompe n'andi majwi kandi bigira ingaruka ku buryo bwo gupima neza.
(3) Igice cy'umuyoboro ugororotse kirakenewe cyane kuri 20D ya mbere na 5D ya nyuma. Bitabaye ibyo, ikwirakwira ry'amazi riba ribi kandi uburyo bwo gupima buragabanuka.
(4) Kutamenya neza uko ibintu bizashyirwa mu bikorwa bizazana ikosa rikomeye mu gupima amazi.
(5) Gupima umuyoboro w'ibipimo bigira ingaruka zikomeye ku buryo ibipimo bipima neza, bigatera amakosa akomeye yo gupima, ndetse nta n'aho amazi agaragara mu bihe bikomeye.
(6) Urwego rw'ubwiringiro n'ubunyangamugayo ntabwo ruri hejuru (muri rusange ni hagati ya 1.5 na 2.5), kandi ubushobozi bwo gusubiramo ni buke.
(7) Igihe gito cyo gukora (ukuri muri rusange gushobora kwemezwa mu gihe cy'umwaka umwe gusa).
(8) Igipimo cy'amazi gikoreshwa mu gupima umuvuduko w'amazi kugira ngo kimenye ingano y'amazi anyuramo, amazi agomba gupima uburemere bw'amazi anyuramo, igikoresho gipima uburemere bw'amazi anyuramo kiboneka binyuze mu gukuba ingano y'amazi anyuramo n'ubucucike bw'amazi bukozwe mu buryo bw'ubukorano, iyo ubushyuhe bw'amazi buhindutse, ubucucike bw'amazi buhinduka, agaciro k'ubucucike bw'amazi gashyirwaho mu buryo bw'ubukorano, ntibishobora kwemeza ukuri kw'ubucucike bw'amazi. Iyo umuvuduko w'amazi upimwe icyarimwe, ubucucike bw'amazi burapimwa, kandi igipimo nyacyo cy'ubucucike gishobora kuboneka binyuze mu kubara.
(9) Ubuziranenge bwo gupima Doppler ntabwo buri hejuru. Uburyo bwa Doppler bukwiriye ibinyabiziga bibiri bifite ibinyabiziga bitandukanye cyane, nk'imyanda yavuwe, ibinyabiziga biva mu ruganda, ibinyabiziga byanduye; Akenshi ntabwo bikwiriye ibinyabiziga bisukuye cyane.
